Zotero File Storage

Zotero File Storage is a cloud-based syncing and storage solution for PDFs, images, web snapshots, and any other files attached to your Zotero libraries. Zotero File Storage synchronizes the files in your personal Zotero library to all your computers, allows you to share the files in your group libraries, and makes files available through the zotero.org website.

Each Zotero user is given 300 MB of free Zotero File Storage, with larger storage plans available for purchase. To check your current usage and/or sign up for additional storage, visit the storage settings of your Zotero account. You can then configure your storage settings through your Zotero client's Sync preferences.

Using Zotero File Storage for Group Libraries

No additional fees are charged for collaboration. Closed public and private groups can use Zotero File Storage for file syncing as long as the group owner has storage space available and has enabled file editing in the group library settings. Group file storage always draws from the storage account of the group owner.
